Mexico enters the 2026 FIFA World Cup as co-host with a clear edge in Group A, reflected in its 52% implied probability, thanks to home-soil matches in Mexico City and Guadalajara plus steady results in recent friendlies under Javier Aguirre. Draws against Portugal and Belgium showcased defensive organization and attacking intent despite key absences. South Korea sits at 19% after heavy warm-up losses to Ivory Coast and Austria that exposed recurring issues in its three-back system and late-game defending. Czechia, at 24.5%, benefits from playoff momentum and recent tactical improvements that have analysts noting its potential to challenge for second. South Africa trails at 5.9% amid ongoing struggles with clinical finishing and inconsistent pressing ahead of its opener against the hosts.
